What mass (in g) of NH3 must be dissolved in 475 g of methanol to make a 0.147 m solution? Group of answer choices 8.42 g 1.90 g 4.94 g 1.19 g 2.02 g
Added by Eduardo L.
Step 1
Given: - Morality (M) = 0.147 mol/L - Mass of solvent (methanol) = 475 g = 0.475 kg Using the formula M = moles of solute / mass of solvent in kg, we can rearrange it to find the moles of NH3: 0.147 mol/L = x mol / 0.475 kg x = 0.147 mol/L * 0.475 kg x = 0.06998 Show more…
