A chemist adds 1.75L of a 4.4/molL sodium nitrate NaNO3 solution to a reaction flask. Calculate the mass in kilograms of sodium nitrate the chemist has added to the flask. Round your answer to 2 significant digits.

___kg

Expert Solution

Step 1

Molarity = Number of moles / Volume in litre

Number of moles = given weight / molecular weight

Number of moles = Volume * Molarity

Volume = 1.75L

Molarity = 4.4 mol/L

Molecular weight of NaNO₃ = 84.99 g/mol
