How can you determine the volume of a gas from the number of moles of a gas (at STP)? Use the pattern you identified in the data table to find the mass of an 89.6 L sample of helium. Helium has a molar mass of 4.0 g/mol.

The table lists pressure and volume values for a particular gas. which is the best estimate for the value of v at p = 7.0 × 103 pascals?

What shape would a molecule with two bound groups and two lone pairs have?

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
