Question

What is the mass in grams of 3.84x10^24 atoms of lead (Pb)? Pb atomic mass is 207.2 g. Express your answer in appropriate number of significant figures.​

Answer 1

Answer:

please make us brinnest

Explanation:

photosynthesis is the process used by plants, algae and certain bacteria to harness energy from sunlight and turn it into chemical energy. Here, we describe the general principles of photosynthesis and highlight how scientists are studying this natural process to help develop clean fuels and sources of renewable energy.

Answer 2

Answer:

pls make me brainliest

and is 3.84*10³g

Explanation:

so we know I mole of any substance =6.022*10²³

so here 207.2g=6.022*10²³ atoms of lead

so 3.84*10²⁴atoms has a mass of 207.2*3.84*10²⁴/2.022*10²³

here let's approximate 2.022 and 207.2 as 2 and 200 respectively so by cancellation we get 3.84*10³g :)
