If a 25 M_$\bigodot$ main-sequence star loses mass at a rate of 10^-6 M_$\bigodot$/yr then how much mass will it lose in its 3-million-year lifetime?

Question

Quizplus · Accepted Answer

To find the total mass lost in a 3-million-year lifetime, we need to multiply the mass loss rate with the time period:

Mass loss = mass loss rate x time period
Mass loss = 10S1U1P1-6S1S1P0 MF1S1S1W1S1U1B1S1U1B0F1F1F10/yr x 3 x 10S1U1P6S1S1P0F10 yr
Mass loss = 3 MF1S1S1W1S1U1B1S1U1B0F1F1F10

Therefore, the star will lose a total of 3 MF1S1S1W1S1U1B1S1U1B0F1F1F10 in its 3-million-year lifetime, which makes the correct answer choice (A).
