The answer is H3PO3.
The formula for phosphorus acid would be H3PO3 assuming that this compound is dissolved in water. <span>This acid is diprotic, not triprotic as might be suggested by this formula. Phosphorous acid is an intermediate in the preparation of other phosphorus compounds.</span>
The total weight of both objects : 7.035 x 10⁻⁸ kg

Given
The weight of a grain of sand : 3.5 x 10⁻¹⁰ kg
The weight of one hair from his eyebrow : 7 x 10⁻⁸ kg
Required
The total weight of both objects
Solution
Scientific Notation consists of 2 parts
1. the first part: the first digit followed by the decimal point
2. The second part: the power of 10 (the exponents).which shows the number of digits after the decimal point
To add/subtract, the exponents must be the same and then add/subtract the coefficient
- convert the largest exponent (7 x 10⁻⁸)
7 x 10⁻⁸ = 700 x 10⁻¹⁰
Geologists look for texture, color, and mineral composition. Since they can be found anywhere such as oceans, deserts, and mountains. <span />
Answer:
0.9612 g
Explanation:
First we <u>calculate how many moles are there in 3.00 g of CCl₃F</u>, using its <em>molar mass</em>:
- 3.00 g CCl₃F ÷ 137.37 g/mol = 0.0218 mol CCl₃F
Now, we need to calculate how many grams of N₂O would have that same number of molecules, or in other words, <em>the same amount of moles</em>.
Thus we <u>calculate how many grams would 0.0218 moles of N₂O weigh</u>, using the <em>molar mass of N₂O</em> :
- 0.0218 mol N₂O * 44.013 g/mol = 0.9612 g N₂O
