Answer:
36.7 M
Explanation:
You have to divide moles with liters.
<span>m = W/g
441 newtons/ 9.8 n/kg = 45 kg</span>
That isn't worded as a question and didn't make sense.
Answer:
(a) 1.95 × 10⁴ g
(b) 1.95 × 10⁷ mg
(c) 1.95 × 10¹⁰ μg
Explanation:
A dog has a mass of 19.5 kg.
<em>(a) What is the dog's mass in grams?</em>
1 kilogram is equal to 10³ grams. The mass of the dog in grams is:
19.5 kg × (10³ g/1 kg) = 1.95 × 10⁴ g
<em>(b) What is the dog's mass in milligrams?</em>
1 gram is equal to 10³ milligrams. The mass of the dog in milligrams is:
1.95 × 10⁴ g × (10³ mg/1 g) = 1.95 × 10⁷ mg
<em>(c) What is the dog's mass in micrograms?</em>
1 gram is equal to 10⁶ micrograms. The mass of the dog in micrograms is:
1.95 × 10⁴ g × (10⁶ μg/1 g) = 1.95 × 10¹⁰ μg
Answer:
Shared (bonding) electrons : 8
Unshared (lone, non-bonding) electrons : 16
Explanation:
The Lewis dot stricture of the molecule attached to this answer shows us all the valence electrons present in the molecule.
Altogether, we have a total number of 24 valence electrons in SO3.
There are eight electrons shared between atoms of elements, these are the bonding electrons.
There are sixteen electrons that are not shared between atoms of elements, These are the lone or non-bonding electrons.
Hence, there are four shared pairs of electrons and eight pairs of unshared electrons.
