Calculate the average atomic mass of carbon if 98.90% of the atoms are C-12 (12.000000 amu) and 1.100% are C-13 atoms (13.003354 amu). Give your answer to the correct number of significant figures.

What is the mass in grams of 9.76 Ã 1012 atoms of naturally occurring lithium?

If water were a linear (not bent) molecule like co2, electrostatic interactions between water molecules would be much weaker. why?

Was the relationship among temperature, heat, and thermal energy?

What will most likely happen when a warmer air mass exists above a polar ice sheet? The temperature of the ice sheet will be lowered. Heat will be transferred from the air mass to the ice. The air mass will exert high pressure and rise upwards.
