What is the velocity of a 0.5-kg ball<br> that has a momentum of 3 kg.m/s?

maria [59]

Answer:

6m/s

Explanation:

Data obtained from the question include:

Mass = 0.5kg

Momentum = 3 kg.m/s

Velocity =.?

Momentum is simply the product of mass and velocity as shown by the equation below:

Momentum = Mass x Velocity

Velocity = Momentum /mass

Velocity = 3kg.m/s / 0.5kg

Velocity = 6m/s

Therefore, the velocity of the ball is 6m/s

You’ve just started a new job in the laboratory of the Food and Drug Administration. Your supervisor asks you to prepare a 1.50-

anastassius [24]

Answer: 118.5 grams

Explanation:

Molarity is defined as the number of moles of solute dissolved per liter of the solution.

$Molarity=\frac{n\times 1000}{V_s}$

where,

n= moles of solute

$V_s$ = volume of solution in ml = 500 ml

$1.50=\frac{moles\times 1000}{500ml}$

moles = 0.75

moles of solute = $\frac{\text {given mass}}{\text {molar mass}}$

0.75 = $\frac{\text {given mass}}{158g/mol}$

mass of $KMnO_4$ = 118.5 grams

Thus mass of $KMnO_4$ needed to prepare 500 mL of this solution iis 118.5 grams
