Una muestra de 02(g) se recoge sobre agua a 24 ºc. el volumen del gas es de 1,16l. en un experimento posterior se determina que la masa de o2 que hay en la muestra es 1,46 g. ¿cual debe haber sido la presión barométrica en el momento en el que se recogió el gas? (presión del vapor de agua = 22,4

The population of unionid mussels decreased after zebra mussels were introduced. zebra mussels competed with the unionid mussels for food. the zebra mussels were able to displace the unionid mussels, allowing the zebra mussel population to increase  over the years. the unionid mussel population decreased because  of lack of food.
