Answer:
*moles = molarity(M=moles/L) * volume (L)
so, you have 4.25 * 0.735 moles
*NH3
* M=n/v
*To determine the number of significant figures in a number use the following 3 rules: Non-zero digits are always significant. Any zeros between two significant digits are significant. A final zero or trailing zeros in the decimal portion ONLY are significant.
Answer:
Bears
Explanation:
because starch is heavy and it requires a lot of oxygen in an environment. so having starch in an environment with less oxygen could probably cause fatigue
Specific Heat-the heat required to raise the temperature of the mass of a substance by a cetain amount
Adhesion-attraction amoung molecules of a different substance.
Cohesion-attraction amoung molecules in a substance
Hydrogen Bonding- a bond between an hydrogen atom and a negative atom
Polar- difference of charge across the molecule

Here the concept of Molarity used .We will put the formula of Molarity then we find moles of copper sulphate .Then we can find the.Given weight of Copper sulphate.So let's do
<h3>
Solution:-</h3>
- Volume of Solvent=0.8L
- Molarity=0.6M
We know
Now
Molar Mass of Solute:-
Now
