Question

If a dust particle has a mass of 7.53×10 raise to power -10 grams , find the weight of 6 lakhs dust particles.​

Answer 1

Answer:

45.18*10^-5 gm

Step-by-step explanation:

1 dust particle has a mass of = 7.53 * 10^-10 gm

6 lakhs dust particle will have mass = 7.53 * 6 * 10^(-10+5)

= 45.18 * 10^-5 gms

Answer 2

Answer:

As one dust particle weighs 7.53×10−10g, so the mass of 6 billion dust particles would be 7.53×10−10g multiplied by 6 lakhs. And then we will have the mass of 6 lakhs dust particles.
