# Mass of Mars is 6.42 × 10^{29} kg and mass of the Sun is 1.99 × 10^{30} kg. What is the total mass?

**Solution:**

Given, the mass of Mars is 6.42 × 10^{29} kg.

The mass of the Sun is 1.99 × 10^{30} kg.

We have to find the total mass.

Total mass = mass of Mars + mass of the Sun

= 6.42 × 10^{29} + 1.99 × 10^{30}

= 6.42 × 10^{29} + 19.9 × 10^{29}

= (6.42 + 19.9) × 10^{29}

= 26.32 × 10^{29} kg

Therefore, the required total mass is 26.32 × 10^{29} kg.
