Solar Energy is the answer
Answer:
This question is incomplete. A fragment of the question is missing. The fragment is:
She finds that 4.87 g of oxygen gas is produced
0.152 moles
Explanation:
Using the formula: mole = mass / molar mass
According to the question, a chemist measures the amount of oxygen gas produced during an experiment. Oxygen gas has the chemical formula: O2. Hence, the molar mass will be:
O2 = 16(2) = 32g/mol
If the mass of the oxygen gas to be 4.87 g of oxygen gas.
Therefore,
moles = 4.87/32
moles = 0.152mol
Answer:
LiCl because the total negative charge on Cl is one.
