Answer:

Volume of the sphere: 3369.3 mm^3

Explanation:

The volume of a sphere is given by the equation:

V=\frac{4}{3}\pi r^3

where:

V is the volume

r is the radius of the sphere

In this problem, we have a sphere with radius:

r = 9.3 mm

Substituting into the previous equation, we can find the volume of the sphere:

V=\frac{4}{3}\pi (9.3)^3=3369.3 mm^3

A piece of metal with a mass of 17.1 g was dropped into a graduated cylinder containing 17.00 mL of water. The graduated cylinde
Mademuasel [1]

The density of the metal with a mass of 1.71g that was dropped into a graduated cylinder containing 17.00 mL of water is 1.005g/mL.

<h3>How to calculate density?</h3>

The density of a substance can be calculated by dividing the mass of the substance by its volume. That is;

Density = mass ÷ volume

According to this question, a piece of metal with a mass of 17.1 g was dropped into a graduated cylinder containing 17.00 mL of water. The density can be calculated as follows:

Density = 17.1g ÷ 17.00mL

Density = 1.005g/mL

Therefore, the density of the metal with a mass of 1.71g that was dropped into a graduated cylinder containing 17.00 mL of water is 1.005g/mL.

Convert 813 torr to kPa
Amanda [17]

Answer: 108.13 kPa

Explanation:

Pressure can be measured in several units such as kilopascal (kPa), torr, atmosphere etc.

Given that:

1 torr = 0.133 kilopascal

813 torr = (813 x 0.133) = 108.13 kPa

Thus, 813 torr is coverted to 108.13 kPa

What is the Ka of a 0.0796 M solution of nitrous acid (HNO2) with a pH of 2.95?
Vadim26 [7]

Answer:

Coefficient = 1.58

Exponent = - 5

Explanation:

pH = 2.95

Molar concentration = 0.0796M

Ka = [H+]^2 / [HA]

Ka = [H+]^2 / 0.0796

Therefore ;

[H+] = 10^-2.95

[H+] = 0.0011220 = 1.122 × 10^-3

Ka = [H+] / molar concentration

Ka = [1.122 × 10^-3]^2 / 0.0796

Ka = (1.258884 × 10^-6) / 0.0796

Ka = 15.815 × 10^-6

Ka = 1.58 × 10^-5

Coefficient = 1.58

Exponent = - 5

What is the half-life of a radioisotope if it decays to 25% of its original activity in 7 yr?
Pepsi [2]

Answer:

3.5 yrs

Explanation:

If a sample has decayed to 25%, this means 2 half-lives have passed. We are given this is equal to 7 yrs, and it follows that one half life is 3.5 yrs.
