Answer:
107g
Explanation:
Magnesium fluoride (MgF₂) has a molecular mass of:
Mg: 24,305 g/mol × 1 = 24,305 g/mol
F: 18,998 g/mol × 2 = 37,996 g/mol
MgF₂ = 24,305g/mol + 37,996g/mol = 62,301g/mol. That means the mass of 1,72 mol of MgF₂ is:
1,72 mol F₂ × (62,301g / 1mol) = <em>107g</em>

Answer:
<u></u>
Explanation:
The current temperature and pressure at <em>STP </em>(Standard Temperature and Pressure) stated by IUPAC are:
- Temperature: 273.15 K (0 °C)
- Pressure: 10⁵ Pa ≈ 0.9869 atm
Using the <em>ideal gas </em>equation, pV = nRT, and the Avogadro constant, you can find the<em> volume occupied by 5.80 × 10²⁰ molecules.</em>

I believe the answer is false
Answer:
I think its epicenter
Explanation:
The epicenter is the point on the earth's surface vertically above the hypocenter, point in the crust where a seismic rupture begins.
