Hello there i am looking for some quick help on this question thank you.

Liquid B has a mass of 75 g and a volume of 25 ml. What is liquid B's density?

1: .33 g/ml

2: 3 g/ml

3: 75 g

4: 25 ml

Un cierto gas tiene un volumen de 800ml a 80°c y 600ml a 80°c y 600mmhg de presión. ¿cual será el volumen del gas a condiciones normales? sí el gas es oxígeno, ¿cuál será su peso? y ¿cuántas moléculas están presentes en el sistema?

What are transitions between a liquid and gas called? identify which way they are transitioning

Mike and mitchell decide to have a foot race. they mark off a stretch of 100 yards, and recruit cindy to work the stopwatch. after running the race and looking at the results, cindy declared that mitchell was the fastest. so how did the boys times compare?
