Explanation:
water near where a river enters the ocean is having a higher density.
coz, ocean water has salt which increases water's density
Sample cost = $15.796
<h3>Further explanation</h3>
Given
Mass = 2 g
Density = 0.718 g/ml
Cost = $5.67 per mL
Required
Cost
Solution
The density : the ratio of mass and volume
Can be formulated :
Density (ρ) = m : V
The volume of the liquid :
V = m : ρ
V = 2 g : 0.718 g/ml
V = 2.786 ml
Sample cost :
= 2.786 ml x $5.67/ml
= $15.796
Answer:
it is false
Explanation:
it goes in different ways not in order
I'm assuming you're asking how to test for a starch,
To do so you do this thing called the "Iodine Test"
The potassium iodide aqueous solution will form this complex with starch to form a purplish-blue color.
However, watch out for the pH as hydrolysis of starch could occur to prevent the test from working out-- and the temperature as the greater it is, the less intense the color is
Answer:
The answer to your question is Molarity = 0.238
Explanation:
Data
Molarity = ?
number of moles = 0.285
volume = 1.2 L
Molarity is a unit of concentration that relates the moles of a substance by the volume in liters.
Formula
Molarity = moles / volume
Substitution
Molarity = 0.285 / 1.2
Simplification and result
Molarity = 0.238
