Answer:
11.7 g in 1 L of water.
Explanation:
Molarity (M) or Molar concentration is a measure used in chemistry for solutes in a solution.
It is defined as mol/ L (number of moles per litre).
0,2 M means we have 0,2 mol/ L
In order to know how many grams this means we need to look up the molecular weight of the solute. In this case NaCl: 58.443 g/mol
= 
X= 
X= 11.69 g
The solution has 11.69 g of NaCl in 1 L of water since its an adequate polar solvent for NaCl dissolution.
Answer:
A
Explanation:
Because there are two DNA strands in the DNA molecule and they both rotate around each other in a helix formation. So two helixes = double helix.
The energy content of food is described in terms of calories because the energy in food ultimately becomes heat.

Photosynthesis is the process through which plants use sunlight and carbon dioxide to make food to sustain themselves. Cellular Respiration is when cells use oxygen and water to create a food source for the cell. The formula for photosynthesis is the same for cellular respiration except it's backwards. Hope this helps.
