Answer:
Oxygen's atomic weight is 16.00 amu. 1 mole of oxygen is 6.02 x 1023 atoms of oxygen 1 amu = 1.661 x 10-24g What is the molar mass (g/mole) of oxygen? Molar mass (in grams) is always equal to the atomic weight of the atom! Molar mass (in grams) is always equal to the atomic weight of the atom!
Answer:
D
Explanation:
The longer handles distribute the force across a longer distance.
Answer:
A
Explanation:
With the given choices, A would be correct for this question. But, both liquids and gases have particles that are far apart so that they can fill their containers.
Answer:
The objects mass is 84, 105 g. See the explanation below, please.
Explanation:
We use the formula:
Density= mass/volume
Mass= Density x volume =0.801 g/mL x 105 mL = 84, 105 g
Answer:
