Answer:
288g
Explanation:
Given parameters:
Number of moles of H₂O = 16moles
Unknown:
Mass of the water = ?
Solution:
To solve this problem, first find the molar mass of H₂O;
Molar mass of H₂O = 2(1) + 16 = 18g/mol
Mass of H₂O = number of moles x molar mass
= 16 x 18
= 288g
Answer:
B
Explanation:
The component carbon (C) has an nuclear number of 6, which suggests that all impartial carbon particles contain 6 protons and 6 electrons. In a commonplace test of carbon-containing fabric, 98.89% of the carbon particles too contain 6 neutrons, so each encompasses a mass number of 12.
Hope that helps
