Salt, salt water are both mixtures if i remember from chemistry
Explanation:
maltose is your answer
hope it's helpful for you
The molecular weight of a substance is calculated by adding the molecular mass of each element present in the molecule multiplied by the number of times each element is in the molecule. For greater clarity, we can organize a table that allows us to do the calculations. We have the following structure for water:
The molecular weight of water will be:
2.01568 + 15.999 = 18.0468=18.0 g/mol
Answer= 18.0
Lithium - Malleable, soft, and shiny
Lead - Opaque solid with higher density
Fluorine - Highly reactive gas
Krypton - Nonreactive gas

Answer:
Bottle is sitting on the shelf for 15 days.
Explanation:
Given data:
Co-60 half life = 5 days
Total amount = 30.0 g
Amount left = 3.75 g
Time taken = ?
Solution:
AT time zero = 30 g
AT first half life= 30g /2 = 15 g
At 2nd half life = 15 g/ 2 = 7.5 g
At 3rd half life = 7.5 g/2 = 3.75 g
Now we will calculate the sitting time of bottle.
Half life = Time taken / number of half lives
3× 5 days = time taken
Time taken = 15 days
Bottle is sitting on the shelf for 15 days.
