I'm having a hard time with this...

...I need help. I want to learn...

Question 1)
The electrolyte from a car battery has H2S04 (aq) concentration of 4.5 per mol and a density of 1.18g per mol.

What is the percentage by mass of H2S04 in the electrolyte?

..I have abt four more questions...

..Help?

The concentration is not specified. 4.5 WHAT per mol of WHAT?

What animal begins with a letter x in it's name?

Sure! I'm here to help. Let's break down your questions one by one.

Question 1:
To find the percentage by mass of H2SO4 in the electrolyte, we need to know the mass of H2SO4 and the total mass of the electrolyte. However, you mentioned that the concentration is not specified. Concentration is usually expressed as mol/L (moles per liter) or similar units. Without the specific concentration, it is difficult to calculate the mass of H2SO4. If you provide the missing information, I can guide you through the calculations.

Question 2:
To explore animal names that begin with the letter "x," there are not many options. One example is the "Xerus," which is a type of ground squirrel found in Africa. Another example is the "X-ray tetra," which is a small tropical freshwater fish. These are just two possibilities, but there may be other animals that start with the letter "x" as well.

If you have the specific concentration for the electrolyte in question 1 or any other questions, please provide that information, and I'll be happy to assist you further.
