Assuming the volume of the insoluble substance to be 92.5 ml and the mass to be 693.8 g, what is the density of the substance? be sure to use the correct number of significant figures. 7.50 g/ml 7.500 g/ml 0.133 g/ml 0.1333 g/ml

Using the density formula: d=m/v.

--> d= 693.8g / 92.5mL

Your answer should be 7.50 g/mL.

7.50 g/ml

Explanation:

Density is the ratio of mass to volume

Density =

Given,

Mass of the substance = 693.8 g

Volume of the substance = 92.5 mL

Density = = 7.50 g/ml

693.8 has 4 significant figures and 92.5 has 3 significant figures. Hence the answer will have the least number of significant figures i.e. 3. So the correct answer is 7.50 g/ml.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
