53.3% + 6.7% = 60%, 100% - 60% = 40%. 40% of glucose is made of carbon. Since there are only three types of atoms in glucose, and the amount of hydrogen and oxygen is already given, this means that whatever percentage is left (40%) has to be carbon.

When 167.2 joules of heat is added to 4.00 grams of water at 10c the resulting temperature is what
Katena32 [7]
Q=mc \Delta T \\\\
Q=168,2J\\
m=4g\\
c=4.184\frac{J}{g^{o}C}\\\\
\Delta T=\frac{Q}{mc}=\frac{167,2J}{4g*4,184\frac{J}{g^{o}C}}=9,99^{o}C\\\\
\Delta T = T_{f}-T_{i}\\\\
9,99^{o}C=T_{f}-10^{o}C\\\\
T_{f}=9,99^{o}C+10^{o}C=19,99^{o}C\approx20^{o}C

3. How many atoms in 3.91 moles of sodium?
Gala2k [10]

Answer:

Explanation:

The formula for sodium is Na. It does not form a molecule in some way.

1 mol Na = 6.02*10^23 atoms

3.91 mol = x                                    Cross multiply

x = 3.91 * 6.02 * 10^23

x = 23.65 * 10^23

x = 2.365 * 10^24

Scientific notation is always expressed as a number 1 ≤ x < 10
