To find the weight of the gas you need to find the number of moles of using ideal gas formula. Remember to change the temperature unit to Kelvin and the pressure to kpa or atm
PV=nRT
n= PV/RT
n= 699 mmHg* 0.1333kpa * 0.357 L/ 8.314 kpa*L / mol*K * (45 +273.15)K
n=<span>0.012 moles
</span>
weight= n * molecular weight
weght= 0.012 *92.448 g/mol= 1.109 grams
To find the density you need to divide mass by volume. When you divide 15g by 14cm^3, you get a density of 1.071g/cm^3. This matches the density of magnesium, so the unknown metal is magnesium.
Primitive cells, for example, yeasts and microscopic organisms utilize all sugars a similar way, gave that they can transport the starch into the cell. Huge atoms that can't be transported are separated remotely by compounds that the cells discharge.
All dietary starch must be processed into little atoms previously assimilation. Those little particles are chiral, pivoting spellbound light to one side or left.
In this order.
protons. 6. carbon atom. different. isotopes. atomic masses. same. chemical reaction. reactions. electrons. neutrons.
