Answer:
Step-by-step explanation:
[0,7)
because the dot is colored in you need to have the bracket
Remember
(ab)/(cd)=(a/c)(b/d)
and

1kg=1000g=1*10^3g
hmm, I estimate, 4 of them
x=number of attoms
mass of 1 times x=1*10^3
3.95*10^-22 times x=1*10^3
divide both sides by 3.95*10^-22
x=

=

=

a million has 9 zeroes
so 24 zeroes is alot that is a <span>septillion, so there are 2.5316 septillion uranium atoms in 1kg
a. 4
b. underestimate
</span>
You put 6 on one side then equal it to 9 with at variable of "X" with it multiplied by 3 to make the thing an equation
Answer:
It’s 4
