Is N2 1 or 2 moles?

You know that one molecule of nitrogen gas, N2 , contains two atoms of nitrogen, 2×N . Now, a mole is simply a very, very large collection of particles. … So, in one mole of nitrogen gas you have 6.022⋅1023 molecules of nitrogen gas, N2 .

What is the formula for moles to grams?

Moles to grams example problem

Solution: Find out the molar mass of the substance (hint: you can use Molar mass of the substance alone to calculate molar mass). The molar mass of KClO3 is 122.548 g/mol. Multiply the given number of moles (2.50 mol) by the molar mass (122.548 g/mol) to get the grams.

How many grams are in 2 moles of NaBr?

1 Expert Answer

We use total molar mass of NaBr to convert from moles of NaBr into grams of NaBr. 22.99+79.90= 102.89 g/mol NaBr. So, there is 226.36 grams of NaBr in 2.20 moles of NaBr.

How do I calculate moles?
