Answer: 448254.609 mm³ OR 4.48 × 10⁵ mm³ </h2>
Explanation:
Volume = Mass ÷ Density
= 0.08 g ÷ 0.17847 g/L
= 0.448254609 L
since 1 L = 1,000,000 mm³
then 0.448254609 L = 448254.609 mm³

Normally you would just use m*c*delta T. But the c is the same in both cases, so you need just use m*deltaT
Givens
25 degrees
m = ?
T = 25
t = final temp = 75
93 degrees
m = 250
T = 93
t = final temp = 75
Solution
(t - 25)*m = (93 - t) * 250 Remove the brackets
75*m - 25m = 93*250 - 250*75 Combine the right
m(75 - 25) = 23250 - 250*75
50 m = 23250 - 18750 Combine
50 m = 4500 Divide both sides by 50
50*m/50 = 4500/50
m = 90
Answer: 90 grams are needed.
