Final answer:
The mass of 1.5x10^5 is 150,000.
Step-by-step explanation:
The given expression has two parts: 1.5, which is the coefficient and 10^5, which represents the power of 10. To find the mass, we multiply the coefficient by 10 raised to the power of the exponent. In this case, the mass is calculated by multiplying 1.5 with 10 raised to the power of 5 (1.5 * 10^5). This gives us a mass of 150,000.
