## How do you convert grams to moles?

Using a calculator, divide the number of grams by the molar mass. The result is the number of moles in your element or compound. For example, imagine you have 2 g of (NH4)2S and you want to convert it to moles. The molecular mass of (NH4)2S is 68.17g/mol.

## How many grams can be produced from moles?

There are three steps to converting grams of a substance to moles: ▪ Step 1: Determine how many grams of a substance are in the problem. Use the periodic table to check the atomic mass, this is the number of grams per mole → 1 mole of Aluminum is 26.982 g ▪ Written as a fraction this is …

## What is the formula for calculating mole?

Use the molecular formula to find the molar mass; to obtain the number of moles, divide the mass of compound by the molar mass of the compound expressed in grams.

## How do I calculate grams?

How to Calculate Grams & Milligrams

- Write, or enter into your calculator, the number of g which you want to convert to mg.
- Multiply the number of g by 1,000. Example: 2.25 g X 1,000 = 2,250 mg.
- Reverse the process to convert mg to g. Divide the number of milligrams by 1,000. Example: 1,250 mg divided by 1,000 = 1.25 g.

## How many moles of P4O10 are there in 50 grams?

The answer is 283.889044. We assume you are converting between grams P4O10 and mole. You can view more details on each measurement unit: molecular weight of P4O10 or mol This compound is also known as Phosphorus Decaoxide. The SI base unit for amount of substance is the mole.

## Is a mole equal to a gram?

Moles of a Substance and the Molecular Weight

The mass of oxygen equal to one mole of oxygen is 15.998 grams and the mass of one mole of hydrogen is 1.008 g.

## How many moles is 25 grams of water?

So, one mole of water has a mass of 16 +1+1 = 18 grams. So, if one mole has a mass of 18 grams, 25 grams would have a mass of 25 grams/ 18 grams per mole or 1.39 moles.

## How many atoms are in a mole?

The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro’s Number (6.0221421 x 1023).

## How many moles of CO2 are there in 132 g?

How many moles are there in 132 g of co2? Therefore 132 g of CO2 contains= 132/44 x 2- moles of oxygen-atom= 6 moles of oxygen-atom.

## How many grams are in 2.5 moles of CO2?

›› More information from the unit converter

The answer is 44.0095. We assume you are converting between grams CO2 and mole. You can view more details on each measurement unit: molecular weight of CO2 or mol This compound is also known as Carbon Dioxide.

## How many moles are in 125g of H2SO4?

The answer is 98.07848. We assume you are converting between grams H2SO4 and mole. You can view more details on each measurement unit: molecular weight of H2SO4 or mol This compound is also known as Sulfuric Acid. The SI base unit for amount of substance is the mole.

## How can I calculate weight?

Summary

- Weight is a measure of the force of gravity pulling down on an object. It depends on the object’s mass and the acceleration due to gravity, which is 9.8 m/s2 on Earth.
- The formula for calculating weight is F = m × 9.8 m/s2, where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms.
