the molar mass of water (h₂o) is 18.02 g/mol. yun has 0.025 mol of h₂o for a laboratory experiment. how many grams of water does she have?\n0.025 g\n0.45 g\n0.90 g\n18 g

the molar mass of water (h₂o) is 18.02 g/mol. yun has 0.025 mol of h₂o for a laboratory experiment. how many grams of water does she have?\n0.025 g\n0.45 g\n0.90 g\n18 g

Answer

Explanation:

Step1: Recall mass - mole formula

Mass = Number of moles×Molar mass

Step2: Substitute given values

Mass of $H_2O=0.025\ mol\times18.02\ g/mol$ Mass of $H_2O = 0.4505\ g\approx0.45\ g$

Answer:

0.45 g
