Answer:
Ok so, I think I have it, but it might not be right, but 16 grams of oxygen
Explanation:
2H+O=H2O
36gH2O x 1mol/18g(molar mass of water)= 2 moles of water
20 grams of H2 x 1/2= 10 moles of H2
2 moles of H2 react with 1 mole of O2 to produce 2 moles of water, so...
1 mole O2 x 16g/mole = 16 g O2
Explanation:
We assume you are converting between grams ZnSO4 and mole. You can view more details on each measurement unit: molecular weight of ZnSO4 or mol This compound is also known as Zinc Sulfate. The SI base unit for amount of substance is the mole. 1 grams ZnSO4 is equal to 0.0061941519772353 mole.
Answer D, aluminum, because the other choices are elements.
Answer:
Mass = 3.24 g
Explanation:
Given data:
Number of atoms of cobalt = 3.31 × 10²² atoms
Mass of cobalt = ?
Solution:
We will calculate the number of moles of cobalt first.
1 mole contain 6.022× 10²³ atoms
3.31 × 10²² atoms × 1 mol / 6.022× 10²³ atoms
0.0549 mol
Mass of cobalt:
Mass = number of moles × molar mass
Mass = 0.0549 mol × 58.93 g/mol
Mass = 3.24 g
