An organic solvent has a density of 1.31g/ml. What volume is occupied by 50.0g of the liquid?

vesna_86 [32]

Answer:

38.16 mL

Solution:

Data Given;

Density = 1.31 g/mL

Mass = 50 g

Volume = ?

Formula Used;

Density = Mass ÷ Volume

Solving for Volume,

Volume = Mass ÷ Density

Putting values,

Volume = 50 g ÷ 1.31 g.mL⁻¹

Volume = 38.16 mL

My name is Ann [436]

Answer:

Uranium-238 undergoes alpha decay to form Thorium-234 as daughter product.

Explanation:

Alpha decay is indicative of loss of the equivalents of a helium particle emission. The reaction equation for this reaction is shown below:

$_{92} ^{238} U_{}$ → $_{90} ^{234} Th_{} + _{2} ^{4} He_{}$

I hope this explanation is clear and explanatory.
