6.28 mol O2 × 2 mol H2 / 1 mol O2 = 12.56 moles H2
The molarity equation states: Molarity = number of moles / volume in liters of solution. Given a molarity of 0.58 M and a beaker volume of 150 mL, we convert it to liters: V (in liters) = 150 mL / 1000 = 0.150 L. Substituting into the formula gives: Number of moles = Molarity * Volume of solution (in liters) = 0.58 * 0.150 = 0.087 moles.
Answer:
Atomic number.
This is because the two values given are 0.05g and 5.20g. This indicates there are two atoms of one element or compound and one of another.
