Answer:
The mass of 16.3 moles of nickel is 956. 647 g.
Explanation:
Given data:
moles of nickel = 16.3 mol
molar mass of nickel = 58.69 g/mol
mass in gram = ?
solution:
Formula:
number of moles = mass / molar mass
mass = number of moles × molar mass
mass = 16.3 mol × 58.69 g/mol
mass= 956. 647 g
Answer:
Volume of the rock, V = 2 mL
Explanation:
It is given that,
Water filled in a graduated cylinder is 3 mL
She then drops a small rock into the cylinder and the water level rises to the 5 mL mark
We need to find the volume of the rock.
The volume of the rock is equal to the difference in volume mark. So,
V = 5 mL - 3 mL
V = 2 mL.
