Step-by-step explanation:
You can see that I put three different forms of answers, but they are all still equivalent answers. The reason why I got three different answers is because I put the inequality in three different calculators and they all got me different answers, but all three are still equivalent. The following three attachments are images of the three calculators that I used to solve.

Answer:
A. 1.8 × Kg
B i. 3.0 × seconds
ii. 9.6 × years
C. After 9.2 × (9.2 billion) years
Step-by-step explanation:
Given that the mass of the Sun = 2× Kg.
Mass of hydrogen when Sun was formed = 76% of 2× Kg
= ×2×
Kg
= 1.52 × Kg
Mass of hydrogen available for fusion = 12% of 1.52 × Kg
= × 1.52 ×
Kg
= 1.824 × Kg
A. Total mass of hydrogen available for fusion over the lifetime of the sun is 1.8 × Kg.
B. Given that the Sun fuses 6 × Kg of hydrogen each second.
i. The Sun's initial hydrogen would last;
= 3.04 × seconds
The Sun's hydrogen would last 3.0 × seconds
ii. Since there are 31536000 seconds in a year, then;
The Sun's initial hydrogen would last;
= 9.640 × years
The Sun's hydrogen would last 9.6 × years.
C. Given that our solar system is now about 4.6 × years, then;
= 2.09
So that; 2 × 4.6 × = 9.2 ×
years
Therefore, we need to worry about the Sun running out of hydrogen for fusion after 9.2 × years.
