What if there was a mole of moles?

It’s really just a number—like “dozen” or “billion.” If you have a mole of something, it means you have 602,214,129,000,000,000,000,000 of them (usually written 6.022times10^{23} ). … It’s such a big number because it’s used for counting numbers of molecules, which there are a lot of.

How fast is a mole?

Deep runways are main passageways that are used daily as the mole travels to and from surface tunnels and its nest. Moles are fast diggers and can tunnel at a rate of 15 feet per hour.

How many moles of Pb NO3 2 are required of 8 moles of AlCl3 are consumed?

From the balanced equation above, 3 moles of Pb(NO3)2 required 2 moles of AlCl3. Xmol of Pb(NO3)2 = 12 moles. Therefore, 12 moles of Pb(NO3)2 are required for the reaction.

How many moles of magnesium phosphate will contain 0.25 mole of oxygen atoms?

Hence, 0.25 moles of oxygen atoms are present in 81×0. 25=3. 125×10−2 moles of magnesium phosphate.

Which has maximum number of molecules?

Since H2 has maximum no. of moles, hence it has maximum no. of molecules.

How do you find the number of moles?

So in order to calculate the number of moles of any substance present in the sample, we simply divide the given weight of the substance by its molar mass. Where ‘n’ is the number of moles, ‘m’ is the given mass and ‘M’ is the molar mass.

How many grams are in 5 moles of lead?

There are ~1040 g of Pb in 5.00 moles.

Which weighs more a mole of copper or a mole of gold?

Answer: Because 1 mole is a fixed quantity of particles (6.022 × 1023 ), 1 mole of copper contains the same number of atoms as 1 mole of gold. Answer: Because each copper atom has less mass than each gold atom, 1 gram of copper contains more atoms than 1 gram of gold.
