Answer:
10.051kg of gold is the mass in kilograms
Explanation:
The density of gold is 19.3g/mL. To solve this question we need to convert the volume of the block of gold to grams using its density. Then, we must convert grams to kilograms using the equivalence factor (1000g = 1kg):
<em>Mass in grams:</em>
520.79mL * (19.3g / mL) = 10051g of gold
<em>Mass in kilograms:</em>
10051g of gold * (1kg / 1000g) = 10.051kg of gold
the water wants to give the electricity to you because it doesn't want any more electrons it throws them away and gives them to your body
Answer:
pH = 4.34
Explanation:
pH= -1/2(logKa) -1/2(log C)
= -1/2( log 5.98*10^-8) -1/2(log 0.0353)
=-1/2(-7.22)-1/2(-1.45)
=3.61+0.725= 4.34
