Answer:- Specific gravity of glucose solution is 1.02.
Solution:- Specific gravity is the ratio of the compound density with water density, means how denser the compound solution is as compared to water.
specific gravity =
density of glucose is given as 1.02 g per mL and water density is 1.00 g per mL.
Let's plug in the values in the formula:
specific gravity = = 1.02
So, the specific gravity of glucose is 1.02. It indicates that glucose is 1.02 times more denser than water.
Answer:
Lithium oxide, Li₂O.
Explanation:
Hello!
In this case, according to the given amounts, it is possible to write down the chemical reaction as shown below:
Which means that the metallic oxide has the following formula: M₂O. Next, we can set up the following proportional factors according to the chemical reaction:
Thus, we perform the operations in order to obtain:
So we solve for x as shown below:
Whose molar mass corresponds to lithium, and therefore, the metallic oxide is lithium oxide, Li₂O.
Best regards!
