Answer:
Explanation:
1 mol of anything is 6.02 * 10^23 (in this case molecules)
x mol has 9.06 * 10^24 molecules of NaNO3
x * 6.02 * 10^23 = 9.06 * 10^24 * 1 Divide by 6.02 * 10^23
x = 9.06 * 10^24/6.02 * 10^23
x = 1.5 * 10
x = 15 mols of NaNO3
1 mol of NaNO3
Na = 23
N = 14
O3 = 48
Total = 85
1 mol of NaNO3 = 85 grams
15 mols = x Cross Multiply
x = 15 * 85
x = 1275 grams
Note: these numbers are approximate but they are very close. You have to use your own values from your periodic table to find the mass of NaNO3. Your answer will be very close to 85.
