What is the volume of 90.0 g of ether if the density of the ether is 0.70 g/mL?
natali 33 [55]
Mass = 90.0 g

Density = 0.70 g/mL

Volume = in mL ?

D = m / V

0.70 = 90.0 / V

V = 90.0 / 0.70

V = 128.57 mL

When 2 grams of Hydrogen (H2) react with 32 grams of Oxygen (O2) the reaction yields hydrogen peroxide (H2O2). How many grams of
Alisiya [41]

<u>Given information:</u>

Mass of H2 = 2 g

Mass of O2 = 32 g

<u>To determine:</u>

Mass of H2O2 produced

<u>Explanation:</u>

The reaction between H2 and O2 can be given as:

H2 + O2 → H2O2

Based on the reaction stoichiometry:

1 mole of H2 reacts with 1 mole of O2 to form 1 mole of H2O2

# moles of H2  = mass of H2 / molar mass of H2 = 2 g/ 2 g.mol-1 = 1 mole

# moles of O2 = mass of O2/ molar mass of O2 = 32 g/ 32 g.mol-1 = 1 mole

Hence for the given reactant conditions, moles of H2O2 produced = 1

Mass of H2O2 = moles of H2O2 * molar mass H2O2 = 1 mole * 34 g.mole-1 = 34 g

<u>Ans</u>: 34 g of H2O2 is produced in this reaction
