How many moles of HCl are in 30.00mL of a 0.1000M HCl solution? A. 0.003000mol. B. 300.0mol C. 0.03000mol D. 3.000mol
Katyanochek1 [597]

Given the volume of HCl solution = 30.00 mL

Molarity of HCl solution = 0.1000 M

Molarity, moles and volume are related by the equation:

Molarity = \frac{Moles of solute}{Volume of solution (L)}

Converting volume of HCl from mL to L:

30.00 mL * \frac{1 L}{1000mL}=0.030000 L

Calculating moles of HCl from volume in L and molarity:

0.03000 L * \frac{0.1000mol}{L}= 0.003000 mol HCl

The final moles would be reported to 4 sig figs. So the correct answer will be 0.03000 mol HCl

Correct option: C. 0.03000mol

¿Cuáles son las ventajas y desventajas entre la agricultura intensiva y la biológica?
SVEN [57.7K]

Answer:

La agricultura intensiva puede eliminar rápidamente los nutrientes del suelo, que generalmente se repara con fertilizantes. La agricultura ecológica normalmente se refiere a no transgénicos

producción y falta de fertilizantes y pesticidas más dañinos. Por lo general, los productos orgánicos se venden a un precio más alto a las personas que creen que los conservantes afectan su salud y bienestar. Los productos intensivos generalmente se venden en grandes cadenas de mercado para obtener grandes ganancias y, por lo general, las frutas transgénicas se pueden producir en casi todas las estaciones.

intensive agriculture can remove nutrients from the soil quickly which is usually remedied by fertilizer. Organic farming normally refers to non-gmo

produce and lack of more harmful fertilizers and pesticides. Usually the organic produce is sold for a higher price to people who believe the preservatives affect their health and well being. Intensive produce is usually sold in large market chains for great profit and usually gmo fruits can be produced in almost all seasons.
