Answer 1

Answer:

The kilogram (also kilogramme) is the base unit of mass in the International System of Units (SI), the current metric system, having the unit symbol kg. It is a widely used measure in science, engineering and commerce worldwide, and is often simply called a kilo in everyday speech.

Answer 2

Given: Given quantities are

1. 450 g flour and 1 L water

2. 500 ml alcohol and 1 L water

3. 300 g rice grains and 540 ml water

4. 450 g sugar and 360 ml coconut milk

5. 50 ml Liquid detergent and 250ml water

To find: We have to find % concentration of the solutions.

Solution:

% of concentration is a ratio of mass of solute to mass of solution multiplied by 100.

1 L water is equal to 1000 gram water. So, mass of solution is 450+1000=1450 gram. % concentration will be

$\frac{450}{1450} \times 100 = 31\%$

2.1 L water will be equal to 1000 ml water. So, mass of solution is 500+1000=1500 L. % concentration will be

$\frac{500}{1500} \times 100 = 33.33\%$

3.1 L water is equal to 1000 gram water. Thus 540ml water will equal to 540 gram water.

So, mass of solution is 540+300=840 gram. % concentration will be

$\frac{300}{840} \times 100 = 35.7\%$

4. 1 L water is equal to 1000 gram water. Thus 360 ml liquid detergent will equal to 360 gram.

So, mass of solution is 450+360=810 gram. % concentration will be

$\frac{450}{810} \times 100 = 55.5\%$

5.Total mass will be 50+250=300ml.

% concentration will be

$\frac{50}{300} \times 100 = 16.66\%$
