Kilogram means 1000 grams
miligram is 1000 in 1 gram
so 1 kilogram is 1000 thousand miligrams or 1 million or 1,000,000 miligrams in 1 kilogram

Sucralfate (molecular weight: 2087g/mol) is a major component of Carafate® which is prescribed for the treatment of gastrointest
maxonik [38]

Answer:

The molarity of the solution is 0.048 M (option B)

Explanation:

<u>Step 1: </u>Data given

Sucralfate has a molar mass of 2087 g/mole

mass = 1g

volume = 10 mL

<u>Step 2: </u> Calculate moles of sucralfate

Number of moles = mass of sucralfate / Molar mass of sucralfate

Number of moles = 1 g / 2087 g/mole = 4.79 * 10^-4 moles

<u>Step 3:</u> Calculate molarity

Molarity = Number of moles / volume

Molarity = (4.79 * 10^-4 moles) / (10 *10^-3 L)

Molarity = 0.0479 M  ≈ 0.048 M

The molarity of the solution is 0.048 M (option B)

A compound has an empirical formula of SO3 and a molecular mass of 152. What is the molecular formula?
Anettt [7]

Answer:

Molecular formula = S₂O ₆

Explanation:

Given data:

Empirical formula = SO₃

Molecular formula = ?

Molecular mass = 152 g/mol

Solution:

Molecular formula = n (empirical formula)

n = molar mass of compound / empirical formula mass

Empirical formula mass  = 80 g/mol

n = 152 g/mol / 80 g/mol

n = 2

Molecular formula = n (empirical formula)

Molecular formula = 2(SO₃)

Molecular formula = S₂O ₆

What happens when you leave sugar and water for a day or two ?
Vikentia [17]

Answer:

For sugar: Studies have shown that (when someone stops eating sugar) there are similar effects as when people get off drugs," she said. "You may experience exhaustion, headaches, brain fog and irritability. Some people even have gastrointestinal distress.

For water: Any deficit in normal body water through dehydration, sickness, exercise or heat stress can make us feel rotten. First we feel thirsty and fatigued, and may develop a mild headache. This eventually gives way to grumpiness, and mental and physical decline
