23 x 10 = 230
Something = 23/10 = 2.3
2.3 x 10 = 23
8.45 x 10^23 = 845,000,000,000,000,000,000,000
There are (6.023 \times 10^{23}) atoms in 1 mole of any substance (Avogadro's number). Therefore, there are (1.004 \times 6.023 \times 10^{23} \approx 6.05 \times 10^{23}) atoms in 1.004 moles of bismuth.
100,000,000,000,000,000,000,000
23 000. This is standard form and should be written as: 23 x 10^2. (The ^ denotes an exponent.)
Three out of 10 students speak Chinese.
There are (6.022 \times 10^{23}) atoms in one mole of carbon. Therefore, in (1.0 \times 10^{-4}) moles of carbon, there would be (6.022 \times 10^{23} \times 1.0 \times 10^{-4} = 6.022 \times 10^{19}) carbon atoms.
5*23*2 = 23*5*2 (commutative property)= 23*(5*2) (associative property) = 23*10 = 230.
There are (~6.022 \times 10^{23}) atoms in one mole of sulfur. Therefore, in 3 moles of sulfur there are (~3 \times 6.022 \times 10^{23} \approx 1.807 \times 10^{24}) atoms of sulfur.
1 mole contains 6.023 times 10^23 atoms....so ......2 moles ...that would be 2 times 6.023 times 10^23 got it?
Oh, dude, let me break it down for you. So, to find out how many times larger 230 is than 23, you just divide 230 by 23, which equals 10. So, 230 is 10 times larger than 23. Like, it's pretty simple math, but hey, I'm here to help.
