a. Lack of OH group on 2′ carbon of the deoxyribose
Answer:
I do believe it would be C. formula
Explanation:
it's a basic thing to any chemical.
The number of moles of the water that was evaporated is 12083467.5 moles of water.
<h3>What moles of water is evaporated?</h3>
We know that the number of moles that we have can be gotten as the ratio of the mass to the number of moles of the object. Now we know that from the question, we have the volume of the hydrogen to be 90,000 gallons. We have to convert this volume to liters.
Given that;
1 gallon = 3.79 L
90,000 gallons = 90,000 gallons * 3.79 L/1 gallon
= 341100 L
Then we have the density of the hydrogen to be 70.85 g/L
Mass of the hydrogen = 70.85 g/L * 341100 L
= 24166935 g
Number of moles of the hydrogen reacted = 24166935 g/2 g/mol
= 12083467.5 moles
If 2 mole of hydrogen gives 2 moles of water
12083467.5 moles of hydrogen gives 12083467.5 moles of water

Answer:
15.75g
Explanation:
Rearrange the formula: density = mass/volume, so that mass is the subject: mass = density × volume
Now substitute (plug in) the known values into the formula:
mass = 10.5 × 1.5 ⇒ mass = 15.75g
The mass of the silver necklace is 15.75g
Hope this helps!
