Perform the following calculations. Express the answers with the correct number of significant figures.

a) \( 7 \, \text{g} - 3.5 \, \text{g} - 2.75 \, \text{g} = \)

b) \( 200.00 \, \text{kg} - 199.0 \, \text{kg} = \)

c) \( 25 \, \text{L} - 3.0 \, \text{L} = \)

d) \( 0.67 \, \text{cm} + 2.0 \, \text{cm} + 0.090 \, \text{cm} = \)

e) \( 104.5 \, \text{g} + 0.40 \, \text{g} = \)

Since there are no conversions to be done just add them as is a) 1 g b) 1.0 kg c) 22 L d) 3.6 cm e) 104.9 g

The answer will be 0.75 gram , 1 kilo- gram , 22 L, 2.76 cm, and 104.9 gram .
What is gram?
A metric unit with mass and weight equal to approximately 15.432 grains, or one-thousandth of a kilo- gram , is called a gram .

Calculation of given question.
a) 7 gram - 3.5 gram - 2.75 gram = 0.75 gram
b) 200.00 kg - 199.0 kg = 1 kilo- gram
c) 25 L - 3.0 L = 22 L
d) 0.67 cm + 2.0 cm + 0.090 cm = 2.76 cm
e) 104.5 g + 0.40 g = 104.9 gram
