Answer: d=2000 g/L
Explanation:
Density is mass/volume. The units are g/L. Since we are given mass and volume, we can divide them to find density. First, we need to convert kg to g.
Now that we have grams, we can divide to get density.
d=2000g/L
Answer:
7.71x10^23 molecules
Explanation:
Avogadro's # = 6.022x10^23
1.28 mol SiO2 x 6.022x10^23/ 1 mol SiO2 = 7.71x10^23 molecules
Answer:
6.64
Explanation:
so moles
then do =4.01×10^24/6.02×10^23
you get the answer as 6.6445 u only need to write the answer to
3.S.F 6.64 moles
hope this make sense :)
