Answer: I believe it is critical mass
Explanation:
Answer: 190 g of magnesium chloride can be produced by reacting 2 moles of chlorine gas with excess magnesium bromide.
Explanation:
The balanced chemical reaction is;
is the limiting reagent as it limits the formation of product and
is the excess reagent.
According to stoichiometry :
1 mole of
produces = 1 mole of
Thus 2 moles of
will produce=
of
Mass of
Thus 190 g of magnesium chloride can be produced by reacting 2 moles of chlorine gas with excess magnesium bromide
Answer:
The scientific laws have been well proven before they are published so it is difficult to prove mistakes
Explanation:
To make 1 Molar solution of hemoglobin ; 1600 grams of hemoglobin will be dissolved in 1 liter of water
The molecular weight of Hemoglobin is approximately 16,000 Daltons, when hemoglobin is converted to mM
16000 Dalton = 16000 ( g/mol )
given that 1 Dalton = 1 g/mol
To make 1 molar solution of hemoglobin using 1 liter of water
1 liter = 1000 grams
16000 Dalton = 16000 g/mol
Hence 16,000 grams of Hemoglobin is required to make 1 Molar solution of hemoglobin using 1 liter of water.

Answer:
4.67 kg
Explanation:
Given data
- Dimensions of the lead sheet: 75.0 cm by 55.0 cm by 0.10 cm
- Density of lead: 11.3 g/cm³
Step 1: Calculate the volume of the sheet
The volume of the sheet is equal to the product of its dimensions.

Step 2: Calculate the mass of the sheet
The density (ρ) is equal to the mass divided by the volume.
