replace mole wid Avogadro number
1 mole = 6.022 × 10^23 items
just like, 1 dozen = 12 items
3.3 moles of Kr = 3.3 x 6.022 × 1023 atoms
Thanks, a bunch. :)
We're did you get1023
Please answer me , I need some clarification .
3.3 moles of Kr = \(3.3 \times 6.022 × 10^{23}\) atoms
its like that
\(1\ mole = 6.022 \times 10^{23} \) atoms
Oh oops ok thank you very much. :)
wlc :)
So the answer is 19x10 to 23 atom According to significant figures
you wanto show it in scientific notation ?
So the answer is 19 x 10 to 23 power According to significant figures
\(3.3 \times 6.022 × 10^{23}\) \(19.8726 \times 6.022 × 10^{23}\) \(1.98726 \times 6.022 × 10^{24}\)
thats scientific notation, we must change that 19.xxxx to 1.9xxxx
Oh yeah forget .....well really once again thank you.
