Answer:
The answer to your question is 2 moles
Explanation:
Data
mass of H₂O = 36 g
moles of H₂O = ?
Process
1.- Calculate the molar mass of water (H₂O)
H₂O = (1 x 2) + (16 x 1) = 2 + 16 = 18 g
2.- Use proportions and cross multiplication to find the answer.
18 g of H₂O ---------------- 1 mol
36 g of H₂O --------------- x
x = (36 x 1) / 18
x = 36/18
x = 2 moles
The answer would be mesons.

<span>the molar mass of H2O can be calculated with the following method:M(H2O)=2x M(H) + M(O), that is because we know that M(H)=1g/mol, M(O)=16g/mol, so M(H2O)=2x1+16=18g/mol, that means 1 mole of H2O contains 18g, so finally one mole of H2O correspond to 18 grams.</span>
Answer: Correct answer is D) Raise the temperature of 1 gram of a substance by 1 degree.
Explanation:
Heat capacity or thermal capacity is a physical property of matter, defined as the amount of heat to be supplied to a given mass of a material to produce a unit change in its temperature. This is rasi
