The density of an alcohol is 0.788 g/mL. What volume in microliters, μL, will correspond to a mass of 20.500 mg? A.
2.60 x 10-2 μL

B.
26.0 μL

C.
16.2 μL

D.
2.60 x 104 μL

B.  26.0 μL.

Explanation:

Hello,

In this case, taking into account that given the mass and density, the volume is computed to be:

Thus, answer is B.  26.0 μL.

Best regards.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong
