Answer: high and low
Explanation: high and low
There is a basic difference, because mass is the actual amount of material contained in a body and is measured in kg, gm, etc. Whereas weight is the force exerted by the gravity on that object mg.

Answer:
A 0.015M
Explanation:
Molarity, which refers to the molar concentration of a solution, can be calculated using the formula:
Molarity (M) = mole (n) / volume (L)
Based on the information provided in this question, the solution contains 0.83 g of dissolved KCI.
We can calculate the number of moles of KCl in the solution by using the formula:
Mole = mass ÷ molar mass
Where atomic mass of; K = 39, Cl = 35.5
Molar Mass of KCl = 39 + 35.5
= 74.5g/mol.
Mole = 0.83g/74.5g/mol.
mole = 0.01114
Approximately, n = 0.011mol
Hence, molarity = 0.011mol/0.75L
Molarity = 0.0146
Molarity = 0.015M
