The formula is density = mass / Volume
density = 1.7 g/mL
mass = 95 grams
Volume = ?
1.7 g/mL = 95 g / Volume
Volume = 95 g / 1.7 g/mL
Volume = 55.88 mL
Hope this help!
Answer:
have the same number of protons
Explanation:
The number of protons in an atom determine what element it is. The number of electrons and neutrons can vary from atom to atom of the element, as long as all the atoms have the same number of protons.
Answer:
We'll have 13.85 grams of potassium
Explanation:
Step 1: Data given
Moles KBr = 0.46 mol
Molar mass KBr = 119.00 g/mol
Molar mass K = 30.10 g/mol
Step 2: The balanced equation
2KBr ⇆ 2K + Br2
Step 3: Calculate moles of K
For 2 moles KBr consumed we'll have 2 moles K and 1 mol Br2
For 0.46 moles KBr we'll have 0.46 moles K
Step 4: Calculate mass of K
Mass K = moles K * molar mass K
Mass K = 0.46 moles * 30.10 g/mol
Mass K = 13.85 grams
We'll have 13.85 grams of potassium
Answer:
Step 1
1 of 2
V = m / D; V (nugget of gold) = 50 g / 5.0 g / cm 3 = 10 cm3; V (nugget of iron pyrite) = 50 g / 19 g / cm3 = 2.63 cm 3
Result
2 of 2
Due to these results you can conclude that nugget of gold which volume is 10 cm3 is bigger than volume of nugget of iron pyrite which is 2.63 cm3.
