@misty1212 could you help?

Answer 1

A closed container has 3.06 ⋅ 1023 atoms of a gas. Each atom of the gas weighs 1.67 ⋅ 10−24 grams. Which of the following shows and explains the approximate total mass, in grams, of all the atoms of the gas in the container?
0.47 grams, because (3.06 + 1.67) ⋅ (1023 ⋅ 10−24) = 4.73 ⋅ 10−1
0.51 grams, because (3.06 ⋅ 1.67) ⋅(1023 ⋅ 10-24) = 5.1102 ⋅ 10-1
4.73 grams, because (3.06 + 1.67) ⋅ (1023 ⋅ 10−24) = 4.73
5.11 grams, because (3.06 ⋅ 1.67) ⋅ (1023 ⋅ 10−24) = 5.1102

Answer 2

HI!!

Answer 3

i can make a guess

Answer 4

the number after the 10's are exponts fyi

Answer 5

first off it is probably \[3.06\times 10^{-23}\] right? and \[1.67\times 10^{-24}\]

Answer 6

correct

Answer 7

on no first one is \[3.06\times 10^{23}\] no minus sign

Answer 8

yea lol forgot

Answer 9

so you have to multiply \[3.06\times 10^{23}\times 1.67\times 10^{-24}\] which is the same as \[\huge (3.06\times 1.67)\times 10^{23-24}\]

Answer 10

need a calculator for the first part for sure

Answer 11

( 5.1102

Answer 12

So then D :D

Answer 13

well maybe \[5.1102\times 10^{-1}\]

Answer 14

5.11 grams, because (3.06 ⋅ 1.67) ⋅ (1023 ⋅ 10−24) = 5.1102

Answer 15

so no, not D

Answer 16

move the decimal over one to the left, gives \[0.51102\]

Answer 17

oh ok then B because of the 10^-1

Answer 18

\[0.51 becasue 5.1102 * 10^-1\]
