Not actually because a solution in math also involves the answer as well as physics.

If you know the mass of an object you can calculate its weight with the formula

Vikki [24]

Answer: True

The formula of weight is w = mg, where m is the mass and g is the acceleration of gravity. If you want to calculate an object's weight, you need to know the two components: mass and gravity.

You only need to know the mass of the object because the acceleration of gravity is ALWAYS (assuming the object is on Earth) 9.8 m/s^2.

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

LUCKY_DIMON [66]

<u>Answer:</u> The mass of solution having 768 mg of KCN is 426.66 grams.

<u>Explanation:</u>

We are given:

0.180 mass % of KCN solution.

0.180 %(m/m) KCN solution means that 0.180 grams of KCN is present in 100 gram of solution.

To calculate the mass of solution having 768 mg of KCN or 0.786 g of KCN (Conversion factor: 1 g = 1000 mg)

Using unitary method:

If 0.180 grams of KCN is present in 100 g of solution.

So, 0.768 grams of KCN will be present in = $\frac{100g}{0.180g}\times 0.768=426.66g$ of solution.

Hence, the mass of solution having 768 mg of KCN is 426.66 grams.
