242 g/mol...... hope it helps :)
In this experiment you will determine the density of an unknown liquid. You will measure the mass of a known volume delivered from a pipet and use the expression:
<span><span><span>M
V</span></span><span>D=</span><span /></span>
where D = density, M = mass and V = volume to calculate the density of the unknown liquid.
Answer:
o increase the rate of chemical reaction
Explanation:
Enzymes are chemical catalysts that speed up chemical reactions by lowering their activation energy. Enzymes have an active site with a unique chemical environment that fits particular chemical reactants for that enzyme, called substrates. Enzymes and substrates are thought to bind according to an induced-fit model.
Answer:
Liquid
Explanation:
If a phase is skipped, the skipped phase will be liquid because it is the only phase between solid and gas.
