In lab you determine the mass of an empty Erlenmeyer flask to be 53.5g. After adding metal, the mass of the flask is now 95.6
You have 865g of NaMnO4 Whats the mass % of oxygen in the compound? A. How many moles of NaMnO4 is that? B.
In lab you determine the mass of an empty Erlenmeyer flask to be 53.5g. After adding metal, the mass of the flask is now 95.6g. After filling the flask up to the top with water, its mass is now 130.0g You then empty the flask and refill it entirely with water. The mass of the flask full of water is 103.5g What is the density of the metal in g/ml? (The density of water is 1.00g/ml).
