The density of a solid object that has a mass of 1.62 lb and a volume of 190 mL is 3.87g/mL.
<h3>How to calculate density?</h3>
Density is the measure of the mass of matter contained by a unit volume. It can be calculated by dividing the mass of the substance by its volume.
According to this question, a solid object is said to have a mass of 1.62 lb and a volume of 190 mL.
1 pound = 453.592 grams
1.62 Ibs is equivalent to 734.82 grams
Density of the solid object = 734.82 grams ÷ 190 mL
Density = 3.87g/mL
Therefore, the density of a solid object that has a mass of 1.62 lb and a volume of 190 mL is 3.87g/mL.

Answer:
Explanation:
Formula
Heat = m * c * delta t
t = temperature in centigrade.
The first thing you have to do is convert kelvin degrees to centigrade. The conversion factor is - 273. The formula is degrees centigrade = degrees kelvin - 273. It is easier to understand with a couple of examples.
- 290o K = 290 - 273 = 17
- 325. K = 325 - 273 = 52
Solution
Heat = 100.0 grams * 4.18 J/g*C * (52 - 17)
Heat = 100 * 4.18 * 35
Heat = 14630 Joules
But you want kj
Heat = 14630 / 100 = 14.63
Answer
Heat = 14.6 kj
