All correct except last option because instantaneous change in acceleration does not change the velocity.
Sample cost = $15.796
<h3>Further explanation</h3>
Given
Mass = 2 g
Density = 0.718 g/ml
Cost = $5.67 per mL
Required
Cost
Solution
The density : the ratio of mass and volume
Can be formulated :
Density (ρ) = m : V
The volume of the liquid :
V = m : ρ
V = 2 g : 0.718 g/ml
V = 2.786 ml
Sample cost :
= 2.786 ml x $5.67/ml
= $15.796
Answer:In a chemistry experiment, 10g of urea, NH2CONH2 (s), is dissolved in 150 mL of water in a simple calorimeter. A temperature decrease of 3.7oC is measured. Calculate the molar enthalpy of solution (∆Hs). ... an ideal gas B if 0.622 g sample of gas B occupies a volume of 300 mL at 35 °C and 1.038 atm.
