Nickel metal has a density of 2.9 g/mL How much does a measured 8.66 ml of nickel metal weigh in mg?
a. 1.4 ×103mg
b. 2.5x10^mg
c. 12 × 10-3mg
d. 12000mg
e. 2400mg
f. none of these
The weight of nickel metal can be calculated using the formula:
weight = volume x density
Plugging in the given values, we get:
weight = 8.66 ml x 2.9 g/ml = 25.114 g
To convert this to milligrams, we multiply by 1000:
weight = 25.114 g x 1000 mg/g = 25114 mg
Therefore, the answer is (f) none of these, as none of the given options match the calculated value.
