To calculate the mass of 5 moles of ice, we first need to determine the molar mass of ice.
Ice is composed of water molecules, and each water molecule consists of two hydrogen atoms (H) and one oxygen atom (O). Given the atomic masses of H = 1 amu and O = 16 amu, we can calculate the molar mass of water (H₂O).
Molar mass of H₂O = (2 * Atomic mass of H) + Atomic mass of O = (2 * 1 amu) + 16 amu = 2 amu + 16 amu = 18 amu
Therefore, the molar mass of water (H₂O) is 18 amu.
Since ice is solid water, it has the same molar mass as water. So, the molar mass of ice is also 18 amu.
To find the mass of 5 moles of ice, we can use the formula:
Mass = Molar mass * Number of moles
Mass of 5 moles of ice = 18 amu * 5 moles = 90 amu
Therefore, the mass of 5 moles of ice is 90 amu.
