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.

Electron configuration
an element A has 3 shells and has 3 valence electrons
so electron configuration of A: 1s², 2s², 2p⁶, 3s², 3p¹
will tend to lose 3 electron to form a cation: A³⁺
a. Nitrate of A
A(NO₃)₃
b. Chloride of A
ACl₃
c. Oxide of A
A₂O₃
Mutualism is the ecological interaction between two organisms.
1. When a big fish eats a tinier fish
2. When a plant absorbs water
Explanation:
Collision theory helps in determining the rate of a reaction as it states that for a reaction to occur it is necessary that there will be number of collisions between reactant molecules.
Therefore, when powdered sugar is placed into water then due to more surface area there will be more number of collisions between sugar and water molecules. As a result, sugar will readily dissolve in water.
On the other hand, surface area of cube will be less as compared to powdered sugar. Hence, there will be less number of collision and cube will take time to dissolve in water.
