Bowling with a volleyball instead of a bowling ball. Will this make it easier or harder to knock over pins?

riadik2000 [5.3K]

Answer:

Definitely harder, since volleyballs are nowhere near as heavy as bowling balls, it’ll be harder too since there wont be much force to knock over pins

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

Ostrovityanka [42]

Answer:

145 grams of a 0.480 % KCN solution contains 697 mg of KCN.

Explanation:

w/w % : The percentage mass or fraction is mass of the of solute present in 100 grams of the solution.

$w/w\%=\frac{\text{Mass of solute}}{\text{Mass of solution}}\times 100$

given = w/w% = 0.480 %

Mass of solute that KCN = 697 mg = 0.697 g

(1 mg = 0.001 g)

Mass of the solution = ? = x

$0.480\%=\frac{0.697 g}{x}\times 100$

$x=\frac{0.697 g}{0.480}\times 100$

x = 145.21 g ≈ 145 g

145 grams of a 0.480 % KCN solution contains 697 mg of KCN.
