Answer:

121.11m/s²

Explanation:

Given parameters:

Force = 525N

Mass = 4.5kg

Unknown:

Acceleration = ?

Solution:

From Newton's second law of motion, we can find the solution to this problem. Using the expression below:

F = m x a

F is the force

m is the mass

a is the acceleration

So'

525 = 4.5 x acceleration

Acceleration = 121.11m/s²

You can practice converting between the mass of a solution and mass of solute when the mass percent concentration of a solution

vfiekz [6]

Answer:

450. g of 0.173 % KCN solution contains 779 mg of KCN.

Explanation:

Mass of the solution = m

Mass of the KCN in solution = 779 mg

Mass by mass percentage of KCN solution = 0.173%

$(m/m)\%=\frac{\text{Mass of solute}}{\text{Mass of solution}}\times 100$

$0.173\%=\frac{779 mg}{m}\times 100$

$m=\frac{779 mg}{0.173}\times 100= 450,289 mg$

1 mg = 0.001 g

m = 450,289 mg × 0.001 g = 450.289 mg ≈ 450. g

450. g of 0.173 % KCN solution contains 779 mg of KCN.

Mention two substance that sublines

Ugo [173]

Familiar substances that sublime readily include iodine , dry ice , menthol, and camphor. Sublimation is occasionally used in the laboratory as a method for purification of solids, for example, with caffeine.

Is particle size one of the factors that affect solubility? How?

Over [174]

Hello!

The reduction in particle size results in an increased rate of solution. It occur because is harder for a a solvent to surround bigger molecules.

Hugs!
