a chemist measures 20.00 moles of water H2O . How many grams of water is that? PLS HELP WILL GIVE BRAINLIST
1 answer:
Answer:
360.4 grams
Explanation:
The first step is to find the molecular mass of H2O. The molecular mass of a molecule is the atomic masses added altogether. Because there are 2 hydrogens, we need 2x the atomic mass. 2(1.01) + 1(16.00) = 18.02 amu.
The molar mass of H2O is 18.02 g/mol. This is the unit converter to change from moles to grams

Explanation:
Limiting reagent is the reagent which limits the formation of product. Excess reagent is one which is in excess and thus remains unreacted.
Thus lithium is the limiting reagent and nitrogen is the excess reagent.
As can be seen from the balanced chemical equation, 6 moles of lithium reacts with 1 mole of nitrogen to give 2 moles of lithium nitride.
Thus 0.578 moles of lithium react with 0.096 moles of nitrogen.
6 moles of lithium give = 2 moles of lithium nitride
Thus 0.578 moles of lithium give= of lithium nitride.
Mass of lithium nitride
Mass of lithium nitride=
The hydrogen bond is a comparatively weak interaction between a proton hop and an electronegative atom present in a molecule. The hydrogen bond plays a very important role for the determination of state of a compound like gaseous, liquid or solid. The strength of the hydrogen bond depends on the close distance between the participants i.e. the electronegative atom and proton hop. There remains strong hydrogen bond between the two water molecules which is expressed as O....H. The distance of the hydrogen bond is 1.8A° formed between each proton hops of two neighboring water molecules. The hydrogen bond interaction is shown in the figure.
