moles = weight (in g) / molecular weight (in g/mol) = 74.3 / 161.97 = 0.46 moles
Oh, dude, let's break it down. So, first off, you gotta calculate the molar mass of Na2CrO4, which is around 205.99 g/mol. Then, you divide the given mass by the molar mass to find the moles. In this case, 74.3 g / 205.99 g/mol gives you approximately 0.36 moles of Na2CrO4. So, there you have it, like, around 0.36 moles of that stuff in 74.3 grams.
Assuming you mean 2.00 M and not 2.00 m, then moles of sodium chromate would be as follows:1.75 L x 2.00 moles/L = 3.50 moles sodium chromate
1 mole is equal to 18 grams of H2O, so 60 grams is 3.33 moles.
The molar mass of gold is approximately 197 grams/mol. To convert moles to grams, you multiply the number of moles by the molar mass. Therefore, 2.8 moles of gold would be approximately 2.8 * 197 = 551.6 grams.
0.1538 grams
