15毫升等于多少克啊?一般一汤匙是15毫升,那15毫升是几克啊?是烧烤酱

包装上有,机洗手洗不同.自己看着来就行

解题思路：俯视凹液面最低处时，所读取刻度在平视凹液面最低处时的上方．量筒的刻度上大下小，故读数比实际体积大（俯大仰小）．

因俯视读数比实际体积大，因此实际体积应比9ml要小，所以实际倒出的溶液体积大于6ml（15ml-9ml）．

点评：
本题考点： 测量容器-量筒；实验数据处理或者误差分析的探究．

考点点评： 本题考查的是量筒使用时，错误的读数方法对结果的影响．倒出溶液后俯视读数，实际倒出的溶液体积比计算体积要大；如果倒出溶液后仰视读数，实际倒出的溶液体积比计算体积要小．

1:600=15：x
x=9000毫升=9升
5:6=10:12
4:9=12:27
所以：苹果树：桃树：梨树=10：:12:27
苹果树=72÷12×10=60棵
梨树=72÷12×27=162棵

1升=1000毫升 0.6升=600毫升
瓶数=600÷15=40瓶
每箱=200×15=3000毫升=3升

画图应给更明了
甲比乙多,甲乙丙之间是有个差的,并且相等 设它为x,
丙加15后,丙变成最多的那个了,甲处在乙丙的之间,所以
3x=15 x=5 所以甲比乙多5毫米

1毫升=1立方厘米
1立方米=1000000立方厘米
15毫升=15立方厘米
把低级单位化成高级单位用低级单位除以进率
15毫升=15÷1000000=0.000015立方米

12分钟.
400-（400+40）÷2=180
180÷15=12

石块的体积＝下降的水的体积，
水面下降
2×4分之1＝0.5分米
石块的体积是
2×2×0.5＝2立方分米

1、铜球体积=水流出的体积=15毫升=15立方厘米
2、4/5=20/25=24/30=0.8

仰视,俯视其实都看的是澳液面.所以仰视看到的实际偏小,而俯视相对偏大.所以最后的结果肯定就偏小,那答案肯定是大于19毫升.

用差量法作
3NO2+H2O=2HNO3+NO
所以缩小2体积气体,有3体积NO2反应,生成1体积NO
所以就是15mL的NO2
也就是原来有10mL的NO
v(NO2)"v(NO)=3:2

1.设甲a,乙b,丙c
2b=a+c
2a=b+c+15
两式相减得a-b=5
所以甲比乙多5

括号添上分数 79立方分米=（ 79/1000）立方米 15毫升=(3/200 )升

15ml/100kg=0.15ml每公斤.1斤=0.5公斤 0.15/2=0.075ml 楼主,每斤加0.075ml

15毫升的试管充满二氧化氮,溶于水剩下5mL NO气体
3NO2+H2O=2HNO3+NO
3 1
15mL V
V=5mL
通入氧气发生反应
4NO+2H2O+3O2=4HNO3
4 3
5mL V
V=3.75mL
这是完全反应充满试管需要的氧气体积,现在还需要5mL氧气,所以是3.75+5=8.75mL

稀释100倍是稀释到100毫升吗?
如果是,每毫升中氯化钾的总量=15000*15/100=2250ug

我也再找

如果是水的话,1升（水）＝1千克（水） 1毫升=1立方厘米=1/1000立方分米
1千克=1000克 1000毫升=1升= 1000克 15毫升=15克

CO2+Na2O2=Na2CO3+1/2O2
NO+1/2O2=NO2
当CO2过量时：
xml的CO2与Na2O2反应生成x/2mlO2,y mlNO与y/2mlO2反应生成y mlNO2
总计气体体积消耗=x/2+y/2=（x+y）/2=30/2=15（ml）
故只要CO2过量即符合要求,四项全部符合选D
如有不懂请追问!

B

规格大于15毫升,且规格离15毫升最近（最好15毫升）.误差小,倒不净的水也少.

∵先仰视读数,读得34毫升
∴实际大于34毫升
∵俯视读数,读得19毫升
∴实际小于19毫升
∴开始：>34ml
倒出后：

要看你和什么反应了.如果和氢氧化钠（一元强碱）,溶液中硫酸是二元强酸,所以反应液呈酸性.

设该硫酸溶液的物质的量浓度为x
15*0.2=10*x
解得x=0.3mol/L

球的体积就是流出的水的体积,及15毫升=15立方厘米

(15mL*0.2mol/L)/10mL=0.3mol/L

设x分钟后两瓶装的葡萄糖相等.
400-15x=40+15x
x=12(分钟)

再加入水100/3毫升 设再加入水X毫升,要保持浓度不变,20/(100+X)=15/100 解得X=100/3

10毫升
