Answer:
Net charge in serine at pH equal to 8.30 is "0"
Explanation:
- At pH >
, carboxyl group exists as
(charged)
- At pH <
- At pH >
(neutral)
- At pH <
(charged)
- So, at pH = 8.30, both carboxyl and amino group exists in charged state.
- Net charge in serine at pH equal to 8.30 is "0".
- Structure of serine at pH equal to 8.30 has been shown below.
5. 25 x 10⁻⁷mg
Explanation:
This is mass conversion from mg to kg;
The kg is a quantity of mass used to measure the amount of matter in a substance.
Given mass = 5.25 x 10⁻¹³kg
The kilo- is a prefix that denotes 10³
therefore;
1000g = 1kilogram
the milli- is a prefix that denotes 10⁻⁻³
1000mg = 1g
Now that we know this, we can convert:
5.25 x 10⁻¹³kg x = 5. 25 x 10⁻¹³ x 10⁶mg
= 5. 25 x 10⁻⁷mg
