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\ndone

Answer

Explanation:

Step1: Recall the mass - mole relationship formula

Mass = Molar mass × Number of moles

Step2: Substitute the given values

Given molar mass of $H_2O$ is $18.02$ g/mol and number of moles is $0.025$ mol. So, mass = $18.02\times0.025$ $18.02\times0.025 = 0.4505\approx0.45$ g

Answer:

B. 0.45 g
