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? 0.025 g 0.45 g 0.90 g 18 g done

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? 0.025 g 0.45 g 0.90 g 18 g done

Answer

Explanation:

Step1: Recall mass - mole formula

Mass = Moles × Molar mass

Step2: Substitute given values

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

Answer:

0.45 g
