Explanation:</h2>
Specific gravity (also called relative density) is the ratio of the density of an object (or substance) to the density of a reference substance (mostly water). It has no unit and is given by the following;
Specific gravity = 
Specific gravity is also given by the ratio of the weight of the object in air to the loss of weight of the object in water. i.e
Specific gravity = 
--------------(* * *)
In this case;
i. The object is the solid which has a weight of 20gf in air.
ii. The loss of weight of the solid in water is the difference between the weight in air (20gf) and the weight in water (18gf).
Therefore the loss of weight is
20gf - 18gf = 2gf
Now substitute these values from (i) and (ii) into equation (* * *) as follows;
Specific gravity = 
Specific gravity = 10
Therefore the specific gravity of the solid is 10

Answer:
A total of 128 characters can be represented in the standard ASCII encoding.
Explanation:
The American Standard Code for Information Interchange (ASCII) was created to make an international standard for encoding the Latin letters. In 1963, ASCII was received so data could be deciphered between PCs; speaking to lower and upper letters, numbers, images, and a few orders.
Since ASCII is encoded using ones and zeros, the base 2 number framework, it uses seven bits. Seven bits permits 2 to the power of 7 = 128 potential blends of digits to encode a character.
ASCII consequently ensured that 128 significant characters could be encoded.
When you are trying to solve a formula like this one, you need to consider the whole row in the spreadsheet, not just A1 and D1.
So, A1:D1 refers to the whole row, which means that you need to add A1+B1+C1+D1 = 2 + 1 + 5 + 3 = 11.
The answer to the formula according to this spreadsheet is 11.
