That is the molecular formula of glucose
The percent concentration of a solution can be calculated from; mass of solute /mass of solution * 100. The mass of the solute here is 8.1 g.
<h3>What is concentration?</h3>
The term concentration refers to the amount of solute presnt in a solution. There are many ways of expressing concentration such as molarity, molality and percentage.
Here;
mass of solution = 230.5 g
Percent of solute = 3.5 %
3.5 = x/ 230.5 * 100
3.5 = 100x/230.5
230.5(3.5) = 100x
x = 230.5(3.5) /100
x = 8.1 g

Answer:
weak acid
Explanation:
pH scale is from 0 to 14
pH =7 is for water which is neutral. it is neither acidic or basic as the hydrogen ion concentration is equal to hydroxyl ion concentration.
Lesser the pH value than 7 greater the acidic nature. And greater the pH value than 7 more the basic nature.
Given pH=3-7 So the indicated interval represents weakly acidic.
The sun is made up of two main elements, hydrogen and helium.
- Hydrogen makes up about 92% of all of the atoms in the sun while helium makes up about 7.8%.
- Oxygen, carbon, neon and nitrogen make up most of the remaining 0.2%.
