1.Which substance has the highest molar mass? Tungsten
Lead
Xenon
Barium
2.At standard temperature and pressure, how many liters of gas are in one mole of that gas?
2.4 L
10.0 L
22.4 L
100.0 L
3. Given the reaction: H₃PO₄ + 3 KOH → K₃PO₄ + 3H₂O If I have 25.0 g of KOH, how much potassium phosphate should I end up with?
4. in the last question, what is the percent yield if I end up with 28.0 g of product?

Answerd. may include all of these are many definitions of bases: the  brønsted-lowry definition of acids and bases says that bases are proton acceptors.the arrhenius definition of acids and bases says that bases increase [oh⁻] in solution (thereby producing oh⁻ ions)the lewis definition of acids and bases says that bases donate electron pairs.therefore, the sensible answer is that a base may include all of the described characteristics.

We first assume that this gas is an ideal gas where it follows the ideal gas equation. the said equation is expressed as: pv = nrt. from this equation, we can predict the changes in the pressure, volume and temperature. if the volume and the temperature of this gas is doubled, then the pressure still stays the same.
